Have you ever had it apart?....the motor should be taken apart and cleaned at least once every two years, more often if you or your camping partner(s) have long hair. Hair is the worst to get clogged in the blades. Simple process...take out the screws and pull it apart. Inspect the impeller (rubber) and clean the blades. Reassemble and you're good to go for another two years. The only fly in the ointment is the large gasket between the two body pieces. That gasket is pretty flimsy and is not sold individually. NAPA sells a roll of gasket material that you can make your own.....Dennis
